WHY AT THE APPLE-TREE A LOT OF PADDERS AND WHAT TO DO?
How to achieve so that there are less windfalls on apple trees? And then we just were tortured to pick apples, among which are both good and rotten.

In order for the fruits of the apple to not fall ahead of time, you need to know the most common causes of this phenomenon. In general, they can be divided into two groups: causes caused by the physiology of the plant itself, and those caused by improper care of the fruit tree.
TOO MUCH "EOODERS"
At the end of June, in apple and pear trees, the phenophase of the physiological abscission of fruit began to reach, which reached the size of hazelnut, especially from trees that are heavily loaded with crops. The reason is in the mismatch of the number of ovaries and the water-food resources of the tree. Present: on the 30-40 tree of thousands of fertilized ovaries. If 10 apples of this variety weigh a kilogram,
then with the safety and full development by the autumn 3-4 tons of fruit will hang on the tree. And will the tree bear such a burden on its “shoulders”? And can it supply such amount of “eaters” with nutrients? This phenomenon is due to the physiology of the plant itself. In this case, we can say that the process of survival is taking place and those fruits of the apple tree that remain on the branches, will absorb the sap of the tree and will delight in ripeness and excellent taste.
If the fallen fruits have already ripened the seeds, and outside the apples are green, then there is nothing to worry about. Collect them and place in a dry and dark place where they mature themselves.
GUILTY PERSONS AND ... AGE
The list of other group of reasons is more extensive. And the main one is the damage to the fruit by pests, in particular, by the moth. A deficiency and an excess of moisture, a lack of nutrients in the soil, weak pollination of flowers and aging of the tree can also cause fruit subsidence.
To keep the apple trees from dropping less, the trees are sprayed with solutions of growth substances. They slow down the formation of a layer of individual cells between the stem and the fruit sprig and thereby increase the strength of attachment to the branches. To do this, use the drugs "Ovary", "Bud", "Epin-extra."
FIGHTING FRUIT FRAMING
An important role in preventing the fruits from shedding is also played by their normalization, which consists in the mechanical removal of small, inconspicuous fruitlets (ovaries). As a result, fewer fruits remain on the tree, but they grow and develop better, their color and taste improve. And the yield is almost not reduced.
Manual normalization of the fruit is recommended at the end of the physiological phase of excess ovary. The developing fruits thin out. In large-fruited varieties, at each fruiting point, one ovary is left, the rest are broken out or cut off. With the frequent location of fruit-bearing rings and a spear of the ovary, leave at intervals of at least 10, see. On the fruit twigs retain one fruit each. On last year's strong shoots with fruit from the lateral buds, the ovaries are left at intervals of 10-20.
It should be noted that normalization slightly reduces the yield per year of abundant fruiting, but improves the quality of the fruits and creates conditions for planting flower buds for the next year's crop.
Constant must be the fight against pests and diseases of the garden. It is not difficult to notice that most often the fallen fruits have moves, gnawed by the moth. Therefore, it is necessary to take a set of measures to combat this pest.
Strengthens fruit fall and fruit rot, which was especially noticeable this year. To protect against excessive shedding of the ovary, after flowering, trees must be fed with slurry diluted with water (1: 1), bird droppings (1: 5) or ammonium nitrate (25-30 g per 10 l of water).
Constantly ensure that the soil is hydrated, especially in dry weather. It is known that an apple tree per year is required from 500 to 1000 l of water. If there is not enough moisture, the tree “pulls” it out of the fruit to saturate the leaves with it. And the fruits fall.
Regularly also thinning and rejuvenating pruning of trees. Well-lit crown and young wood contribute to the accumulation of plastic substances, which also hinders the premature abscission of fruits.
